181    will try to build the C++ wrapper.    --disable-shared
182      --disable-static
183  . If you want to make use of the support for UTF-8 character strings in PCRE,  
184    you must add --enable-utf8 to the "configure" command. Without it, the code    (See also "Shared libraries on Unix-like systems" below.)
185    for handling UTF-8 is not included in the library. (Even when included, it  
186    still has to be enabled by an option at run time.)  . By default, only the 8-bit library is built. If you add --enable-pcre16 to
187      the "configure" command, the 16-bit library is also built. If you add

194      command. Otherwise, when "configure" is run without --disable-pcre8, it will
195      try to find a C++ compiler and C++ header files, and if it succeeds, it will
196      try to build the C++ wrapper.
197    
198    . If you want to include support for just-in-time compiling, which can give
199      large performance improvements on certain platforms, add --enable-jit to the
200      "configure" command. This support is available only for certain hardware
201      architectures. If you try to enable it on an unsupported architecture, there
202      will be a compile time error.
203    
204    . When JIT support is enabled, pcregrep automatically makes use of it, unless
205      you add --disable-pcregrep-jit to the "configure" command.
206    
207    . If you want to make use of the support for UTF-8 Unicode character strings in
208      the 8-bit library, or UTF-16 Unicode character strings in the 16-bit library,
209      or UTF-32 Unicode character strings in the 32-bit library, you must add
210      --enable-utf to the "configure" command. Without it, the code for handling
211      UTF-8, UTF-16 and UTF-8 is not included in the relevant library. Even
212      when --enable-utf is included, the use of a UTF encoding still has to be
213      enabled by an option at run time. When PCRE is compiled with this option, its
214      input can only either be ASCII or UTF-8/16/32, even when running on EBCDIC
215      platforms. It is not possible to use both --enable-utf and --enable-ebcdic at
216      the same time.
217    
218    . There are no separate options for enabling UTF-8, UTF-16 and UTF-32
219      independently because that would allow ridiculous settings such as requesting
220      UTF-16 support while building only the 8-bit library. However, the option
221      --enable-utf8 is retained for backwards compatibility with earlier releases
222      that did not support 16-bit or 32-bit character strings. It is synonymous with
223      --enable-utf. It is not possible to configure one library with UTF support
224      and the other without in the same configuration.
225    
226    . If, in addition to support for UTF-8/16/32 character strings, you want to
227      include support for the \P, \p, and \X sequences that recognize Unicode
228      character properties, you must add --enable-unicode-properties to the
229      "configure" command. This adds about 30K to the size of the library (in the
230      form of a property table); only the basic two-letter properties such as Lu
231      are supported.

240      --enable-newline-is-any to the "configure" command, respectively.
241    If you specify --newline-is-cr or --newline-is-crlf, some of the standard  
242    tests will fail, because the lines in the test files end with LF. Even if    If you specify --enable-newline-is-cr or --enable-newline-is-crlf, some of

246      --enable-newline-is-any, many tests should succeed, but there may be some
247      failures.
248    
249    . By default, the sequence \R in a pattern matches any Unicode line ending
250      sequence. This is independent of the option specifying what PCRE considers to
251      be the end of a line (see above). However, the caller of PCRE can restrict \R
252      to match only CR, LF, or CRLF. You can make this the default by adding
253      --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").

304      discussion about stack sizes in the pcrestack man page.
305    
306    . For speed, PCRE uses four tables for manipulating and identifying characters
307      whose code point values are less than 256. By default, it uses a set of
308      tables for ASCII encoding that is part of the distribution. If you specify
309    
310      --enable-rebuild-chartables
311    
312      a program called dftables is compiled and run in the default C locale when
313      you obey "make". It builds a source file called pcre_chartables.c. If you do
314      not specify this option, pcre_chartables.c is created as a copy of
315      pcre_chartables.c.dist. See "Character tables" below for further information.
316    
317    . It is possible to compile PCRE for use on systems that use EBCDIC as their
318      character code (as opposed to ASCII/Unicode) by specifying
319    
320      --enable-ebcdic
321    
322      This automatically implies --enable-rebuild-chartables (see above). However,
323      when PCRE is built this way, it always operates in EBCDIC. It cannot support
324      both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25,
325      which specifies that the code value for the EBCDIC NL character is 0x25
326      instead of the default 0x15.

332      PCRE will use valgrind annotations to mark certain memory regions as
333      unaddressable. This allows it to detect invalid memory accesses, and is
334      mostly useful for debugging PCRE itself.
335    
336    . In environments where the gcc compiler is used and lcov version 1.6 or above
337      is installed, if you specify
338    
339      --enable-coverage
340    
341      the build process implements a code coverage report for the test suite. The
342      report is generated by running "make coverage". If ccache is installed on
343      your system, it must be disabled when building PCRE for coverage reporting.
344      You can do this by setting the environment variable CCACHE_DISABLE=1 before
345      running "make" to build PCRE.
346    
347    . The pcregrep program currently supports only 8-bit data files, and so
348      requires the 8-bit PCRE library. It is possible to compile pcregrep to use
349      libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by
350      specifying one or both of
351    
352      --enable-pcregrep-libz
353      --enable-pcregrep-libbz2
354    
355      Of course, the relevant libraries must be installed on your system.
356    
357    . The default size of internal buffer used by pcregrep can be set by, for
358      example:
359    
360      --with-pcregrep-bufsize=50K
361    
362      The default value is 20K.
363    
364    . It is possible to compile pcretest so that it links with the libreadline
365      or libedit libraries, by specifying, respectively,
366    
367      --enable-pcretest-libreadline or --enable-pcretest-libedit
368    
369      If this is done, when pcretest's input is from a terminal, it reads it using
370      the readline() function. This provides line-editing and history facilities.
371      Note that libreadline is GPL-licenced, so if you distribute a binary of
372      pcretest linked in this way, there may be licensing issues. These can be
373      avoided by linking with libedit (which has a BSD licence) instead.
374    
375      Enabling libreadline causes the -lreadline option to be added to the pcretest
376      build. In many operating environments with a sytem-installed readline
377      library this is sufficient. However, in some environments (e.g. if an
378      unmodified distribution version of readline is in use), it may be necessary
379      to specify something like LIBS="-lncurses" as well. This is because, to quote
380      the readline INSTALL, "Readline uses the termcap functions, but does not link
381      with the termcap or curses library itself, allowing applications which link
382      with readline the to choose an appropriate library." If you get error
383      messages about missing functions tgetstr, tgetent, tputs, tgetflag, or tgoto,
384      this is the problem, and linking with the ncurses library should fix it.

645    RunTest uses a file called testtry to hold the main output from pcretest.
646    Other files whose names begin with "test" are used as working files in some

753    attention to the LC_xxx environment variables. In other words, it uses the
754    system's default locale rather than whatever the compiling user happens to have
755    set. If you really do want to build a source set of character tables in a
756    locale that is specified by the LC_xxx variables, you can run the dftables
757    program by hand with the -L option. For example:
